What it is: Chevy’s restyled B-segment car, which will slot into the lineup between the upcoming Spark and Cruze. The concept shown in Detroit featured an aggressive fascia, 19-inch wheels and tires, various aerodynamic add-ons, and a modified interior that would likely be featured on an RS version of the Aveo, should Chevy build it.

Why it matters: All automakers need small cars in their product mix to help meet the tougher CAFE standards of the future. Aveo production moves from Korea to the U.S. Currently, its big appeal is its little price; Chevy needs to sex up the Aveo so it can compete with the likes of Ford’s new Fiesta.

Platform: The Aveo is engineered by GM’s Daewoo subsidiary in Korea and rides on an updated version of the current platform.

Powertrain: If the RS makes it to production, a 138-hp, 1.4-liter turbocharged four-cylinder—shared with the Chevy Cruze—is possible. Regular Aveos are likely to get a slightly more powerful version of the current car’s 108-hp, 1.6-liter four.
